This is the first series of patches that tries to cleanup emulator code.
This is mix of bug fixes and moving code that does emulation from x86.c
to emulator.c while making it KVM independent. The status of the patches:
works for me. realtime.flat test now also pass where it failed before.
Gleb Natapov (24):
KVM: Remove pointer to rflags from realmode_set_cr parameters.
KVM: Provide callback to get/set control registers in emulator ops.
KVM: remove realmode_lmsw function.
KVM: Provide current CPL as part of emulator context.
KVM: Provide current eip as part of emulator context.
KVM: x86 emulator: fix mov r/m, sreg emulation.
KVM: x86 emulator: fix 0f 01 /5 emulation
KVM: x86 emulator: 0f (20|21|22|23) ignore mod bits.
KVM: x86 emulator: inject #UD on access to non-existing CR

KVM: Use task switch from emulator.c
KVM: x86 emulator: fix in/out emulation.
KVM: x86 emulator: Move string pio emulation into emulator.c
KVM: x86 emulator: remove saved_eip
